Bomb squad closes Palo Alto street, dismantles mortar

World War II shell found in Adobe Meadow garage by homeowner

Discovery of a World War II-era Japanese mortar forced the closure of part of Grove Avenue in Palo Alto Monday morning (Oct. 3).

Hal Knowlton, 87, found the 3-inch-diameter shell while cleaning his garage. He took the mortar outside and set it on the planter box, then returned to his home to call police, he said.

"I thought it'd just be boom-boom -- they would just take it away. But the policewoman said, 'Oh, this is going to be a production,'" Knowlton said.

Police closed off the 3800 block of Grove and notified nearby residents of the quiet street they might have to evacuate. The Santa Clara County Sheriff's bomb squad arrived and dismantled the mortar, which Knowlton estimated was about 9 to 10 inches long.

Palo Alto police Officer Marianna Villaescusa said the mortar still contained some powder but it was determined to be inert.

Knowlton said he and his wife have lived in the house since 1966. He served in the Navy and was assigned to the Pacific on Gen. Douglas MacArthur's command ship. It was the seventh ship to arrive in Tokyo after the war, he said.

"I have no idea of how it got there. I never envisioned this," he said, as neighbors teased him about causing a neighborhood ruckus. "There has not been so much excitement since our neighbor fell out of the persimmon tree and he wouldn't get into the ambulance," he said.

Hmmm .. WWII-era mortar shell, WWII-era home owner who served in Japan .. if this fellow didn't bring this bit of history home to the US .. who else living in that house might have?

I never know which bin to use for old war relics: green yard waste ( if dug up in the yard), blue recycling (for metal recycling) or black garbage!

Once I learned that people were safe, this story made me laugh. It reminded me of the PA I knew as a, not during WWII, but w/that smaller town sensibility that, aside from its subject, is in this story. Loved his quote about the persimmon tree :-)

This was a great story!

You have to wonder where that mortar shell came from. Is it possible that this veteran didn't know he had it in his WWII Navy knapsack and just now got around to cleaning it out? Now, he bought the home in 1966, so perhaps the previous owner was a vet as well?

But, I agree that the quote about the man falling out of the Persimmon tree was very, very funny!

Just learned something interesting from one of the park rangers up at Foothill Park~
During the WW1, there was live ammo that was placed around in Foothills park..(it was for training exercises for the dog sniffing dogs to locate~).
Even as current as a few years ago there has been some shells found in the park. The original papers that showed where shells (etc.) were placed was "destroyed" and some were left behind.......................
